Rails                  
                                          
                                          
  
                                          
  
                                          
                                          
 Trains  Are  So  Constructed  That  They 
 Have To Follow A Set  Path. This Path Is 
 Called A  "Railway", Which  Is Comprised 
 Of Two Metal  Rails, Hence Its Nickname. 
                                          
 Because The  Low  Friction  Between  The 
 Wheels Of  The Train And The Rail Metal, 
 There Are Limits  For How Acute  A Curve 
 Can  Be, And  Even More  So For How Much 
 The   Ground  Under  The  Rails  Can  Be 
 Sloped. Thus A Railway Is Often Not  Led 
 On  Top Of Hills, Rather Through Them In 
 TunnelS  (If   They   Are   Large),   Or 
            Artificial ChasmS.            
                                          
 There Will Be  Trees  On The Side Of The 
 Rails, But  Not Too Close, Or They  Will 
 Be  Cut Down  By  The  Railway Janitors. 
 There  Will  Be Plains,  And  Bodies  Of 
                  Water.                  
                                          
 Trains  Go By  Day  And By Night.  Along 
      The Way, There Is Information       
 Scattered, Often  Put  On Top  Of Poles, 
 To Be Interpreted By  The Train Drivers. 
 Different  Parts  Of  The  Railway  Have 
          Different Speed Limits.         
                                          
 Sometimes, Trains Have To Stop  And Wait 
 For Something To Happen,  Far Away. This 
 Is  Signaled  By  Red  Or Green  Lights. 
                                          
                                  
                                          
 Many People Follow  The  Rails  By Foot. 
 Often  This  Proves  To  Be  The Shorter 
 Path Between  Two Points.  However  This 
 Is  Frowned   Upon,  And  Very  Impolite 
        Toward The Train Drivers!
